From: Robert Haas Date: Thu, 2 Feb 2017 19:40:05 +0000 (-0500) Subject: Increase upper bound for bgwriter_lru_maxpages. X-Git-Tag: REL_10_BETA1~963 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=14ca9abfbe4643408ad6ed3279f2f6366cafb3f1;p=thirdparty%2Fpostgresql.git Increase upper bound for bgwriter_lru_maxpages. There is no particularly good reason to limit this value to 1000, so increase the limit to INT_MAX / 2, the same limit we use for shared_buffers. It's not clear how much practical effect larger settings will have, but there seems no harm in letting people try it. Jim Nasby, less a comment change I stripped out.
